Description:

Continuous monitoring of water is of the highest priority to ensure environmental compliance, as well as performance of numerous industrial processes. One of the most difficult and critical parts of continuous water analysis is the determination of metal ion concentrations. Even at trace levels, metal ions can ruin various industrial processes, and cause serious damage to the environment. ECI Technology, Inc., has developed:

  1. the stripping voltammetry method and
  2. a technique of electrochemical sample preparation, which are used for laboratory determination of trace levels of metals in various solutions.

The proposed system will be based on these as well as other electrochemical techniques. Phase I research will address the following issues:

  1. interference by various inorganic and organic substances on continuous stripping voltammetry determination of copper, lead(II) and cadmium ions in the standard solutions;
  2. feasibility of techniques to eliminate the interference;
  3. test of proposed system with samples of actual drinking, natural and industrial waters.

Continuous and complete information of water composition will:

  1. prevent the pollution of water and food products,
  2. prevent rejects in industries, and
  3. create the foundation for an automated control of industrial processes, as well as waste and drinking water treatment systems.
